Spawned processes and inter-communicators ?

Hi

here's my problem.

Suppose, we have one task that calls "MPI_Spawn" twice to spawn two sets
of processes.
For each set of processes, an inter-communicator will exist in order to
send/receive messages to/from its father. (thanks to MPI_Comm_parent).

Suppose now, that the first set of spawned processes needs to send/receive
messages to/from the other set of spawned processes.

How can I do that ?
I did not see any hints about that in the current version of the "dynamic
process" chatper of MPI-2.
